Description

Technical Field

[0001] This invention relates to the field of refrigerator technology, and more specifically, to a refrigerator start-up control method and device, a refrigerator, a storage medium, and electronic equipment. Background Technology

[0002] In air-cooled refrigerators, the freezer compartment acts as the cold source, supplying cooling to the refrigerator compartment via an air duct system. The compressor's start and stop are typically determined by the freezer temperature, while temperature fluctuations in the refrigerator compartment have a relatively small impact on compressor operation. However, as the refrigerator ages, its insulation performance may decline, for example, due to aging door seals or insulation materials, causing the refrigerator compartment temperature to rise too quickly. In this case, the freezer compartment needs to frequently supply cooling to maintain the refrigerator compartment temperature, leading to increased compressor operating frequency and higher overall energy consumption. Furthermore, excessive temperature fluctuations between the refrigerator and freezer compartments can negatively impact food preservation and reduce user experience.

[0029] This embodiment provides a refrigerator start-up control method. Figure 2 This is a flowchart of a refrigerator start-up control method according to an embodiment of the present invention, such as... Figure 2 As shown, the process includes the following steps: Step S202: When the refrigerator compressor is off, detect the first real-time freezing temperature of the freezer compartment and the first real-time refrigeration temperature of the refrigerator compartment, wherein the refrigerator includes the refrigerator compartment and the freezer compartment; In this embodiment, the freezer compartment of the refrigerator is the cold source for the refrigerator compartment. The freezer compartment and the refrigerator compartment are connected by a cooling duct. When the real-time temperature of the refrigerator compartment is higher than the preset refrigerator start-up temperature, the cooling duct is opened, and the freezer compartment delivers cold energy to the refrigerator compartment to reduce the real-time temperature of the refrigerator compartment. During this period, the real-time temperature of the freezer compartment will rise.

[0030] In this embodiment, when the real-time temperature of the freezer compartment rises and exceeds the preset freezer start-up temperature, the compressor is activated to cool the freezer compartment, thereby meeting the cooling needs of the entire refrigerator.

[0031] Step S204: Obtain the insulation parameters of the refrigerator, wherein the insulation parameters are used to characterize the insulation capacity of the refrigerator; Optional, insulation parameters may include, but are not limited to: manufacturing date, the time the refrigerator door is opened during the current downtime, and the temperature of the food inside the refrigerator.

[0032] Step S206: Control the compressor to start in advance based on the first real-time freezing temperature, the first real-time refrigeration temperature, and the insulation parameters.

[0033] Through the above steps, when the refrigerator compressor is off, the first real-time freezing temperature of the freezer compartment and the first real-time refrigeration temperature of the refrigerator compartment are detected, wherein the refrigerator includes the refrigerator compartment and the freezer compartment; the insulation parameters of the refrigerator are obtained, wherein the insulation parameters are used to characterize the insulation capacity of the refrigerator; the compressor is controlled to start in advance based on the first real-time freezing temperature, the first real-time refrigeration temperature, and the insulation parameters. By introducing the refrigerator's refrigeration temperature and insulation parameters, the freezer start-up temperature can be appropriately corrected and the compressor can be controlled to start in advance, which can compensate for the insufficient cold supply caused by the decline in the refrigerator's insulation performance, thereby reducing the temperature fluctuation of the refrigerator. This solves the technical problem of large temperature fluctuations in the compartments caused by poor refrigerator insulation performance in related technologies, avoids cold supply lag and temperature fluctuations caused by the decline in refrigerator insulation performance, and improves the refrigerator's cooling effect and user experience.

[0034] In one embodiment of this example, controlling the compressor to start based on the first real-time freezing temperature, the first real-time refrigeration temperature, and the insulation parameter includes: determining whether the refrigeration compartment meets the refrigeration start-up conditions based on the first real-time refrigeration temperature; if the freezing compartment meets the refrigeration start-up conditions, determining the freezing start-up temperature of the freezing compartment, and calculating the start-up compensation temperature based on the insulation parameter, wherein the start-up compensation temperature is less than 0; correcting the freezing start-up temperature using the start-up compensation temperature to obtain a target start-up temperature; determining whether the first real-time freezing temperature is greater than or equal to the target start-up temperature; if the first real-time freezing temperature is greater than or equal to the target start-up temperature, controlling the compressor to switch from a stopped state to a started state.

[0035] In this embodiment, the refrigeration start-up condition is the opening of the air ducts in the freezer and refrigerator compartments. When the refrigeration start-up condition is met, the refrigerator compartment has a cooling demand, and the freezer compartment is providing cooling to the refrigerator compartment.

[0036] In one example, the refrigerator's set temperature for the refrigerator compartment is 5°C, the set temperature for the freezer compartment is -15°C, the freezer start-up temperature is -12°C, and the range of the start-up compensation temperature can be set from -2°C to 0°C. For example, when the start-up compensation temperature is calculated to be -1°C based on the insulation parameters, the freezer start-up temperature is corrected using the following formula: freezer start-up temperature + start-up compensation temperature = target start-up temperature. Since the start-up compensation temperature is less than 0, the target start-up temperature is less than the (uncorrected) freezer start-up temperature. The corrected freezer start-up temperature (target start-up temperature) is calculated to be -13°C. Taking a real-time freezer temperature of -15°C as an example, the freezer compartment starts to rise from -15°C. When it rises to -13°C (without waiting for the freezer compartment to rise to -12°C), the first real-time freezer temperature is greater than or equal to the target start-up temperature, and the compressor is controlled to switch from the off state to the start state. By reducing the freezer start-up temperature, the compressor can be started earlier.

[0037] The solution in this embodiment corrects the start-up temperature of the freezer compartment by using start-up compensation temperature, so that the target start-up temperature obtained after correction is lower than the start-up temperature of the freezer compartment. This can achieve the effect of starting the compressor earlier and prevent excessive temperature fluctuations in the freezer compartment.

[0038] Optionally, determining whether the refrigerator compartment meets the refrigeration start-up conditions based on the first real-time refrigeration temperature includes: determining the refrigeration start-up temperature of the refrigerator compartment; determining whether the first real-time refrigeration temperature is greater than the refrigeration start-up temperature; if the first real-time refrigeration temperature is greater than the refrigeration start-up temperature, determining that the refrigerator compartment meets the refrigeration start-up conditions, and controlling the freezer compartment to cool the refrigerator compartment.

[0039] In one example, the set temperature of the refrigerator compartment is 5°C, and the refrigerator start-up temperature is 6°C. When the temperature of the refrigerator compartment fluctuates and cold energy overflows, if the real-time refrigerator temperature is greater than 6°C, the control system determines the refrigerator start-up condition and controls the freezer compartment to cool the refrigerator compartment. If the air vent between the freezer and refrigerator compartments is opened, since the real-time temperature of the freezer compartment is lower than that of the refrigerator compartment, cold energy can be transferred to the refrigerator compartment, lowering the real-time temperature of the refrigerator compartment. At the same time, the temperature of the freezer compartment will rise.

[0040] The solution in this embodiment determines whether the refrigerator compartment meets the conditions for refrigeration to start. When the refrigerator compartment meets the conditions for refrigeration to start and has a refrigeration demand, the freezer compartment needs to provide cooling capacity to the refrigerator compartment. This determines the situation where the temperature of the freezer compartment will fluctuate significantly, thus avoiding starting the compressor in advance when the temperature of the freezer compartment will not fluctuate significantly, and reducing the compressor's starting frequency.

[0041] In one implementation scenario, calculating the start-up compensation temperature based on the insulation parameters includes: determining whether the refrigerator's manufacturing date is greater than a preset number of years, wherein the insulation parameters include the manufacturing date; if the refrigerator's manufacturing date is greater than the preset number of years, calculating the start-up compensation temperature based on the manufacturing date, wherein the manufacturing date is negatively correlated with the start-up compensation temperature.

[0042] In this implementation scenario, the insulation parameters are related to the refrigerator's manufacturing date. Even during a power outage, the timer on the refrigerator's mainboard (equipped with a battery) keeps track of the temperature and stores the data in the mainboard's registers. The refrigerator's manufacturing date can be read from the mainboard's registers.

[0043] In one example based on this implementation scenario, the system continuously monitors whether the refrigerator is disconnected from the main power supply to determine if battery power needs to be cut off. If so, the mainboard MCU enters low-power mode, and the main controller MCU is powered by the battery and activates low-power mode to save battery power. The battery power circuit is disconnected, and the refrigerator is powered by the mainboard power supply to save battery power. The refrigerator's manufacturing time Y is recorded in real time to determine if the refrigerator is too old. The system checks if the manufacturing time Y is less than a threshold Y0 (typically 10 years). The preset age is Y0. If so, it indicates that the refrigerator's insulation performance is good, and no start-up compensation temperature needs to be set. The freezer compartment start-up compensation temperature setting is then implemented. Let Tfrz0 be the factory date of the refrigerator (typically 0 degrees Celsius). Then, determine if the factory date Y is greater than the threshold Y0 and less than the threshold Y1 (typically 15 years). If so, it means that the refrigerator's insulation performance has declined and the start-up compensation temperature needs to be increased appropriately. The freezer compartment stop-loss compensation temperature is set to Tfrz1 (typically -0.5 degrees Celsius). Otherwise, if the factory date Y is greater than or equal to the threshold Y1, the refrigerator has been used for too long and its insulation performance is even worse. A higher start-up compensation temperature is needed to meet the temperature fluctuation requirements. The freezer compartment stop-loss compensation temperature is set to Tfrz2 (typically -1 degree Celsius).

[0044] The solution in this embodiment uses the manufacturing date as a thermal insulation parameter to calculate the start-up compensation temperature for triggering the compressor to start in the freezer compartment. The longer the manufacturing date, the smaller the start-up compensation temperature and the longer the compressor starts in advance. This can compensate for the decrease in thermal insulation capacity and loss of cold energy caused by refrigerator aging, and solve the problem of temperature fluctuation in the refrigerator compartment caused by the lag in cold energy due to refrigerator aging.

[0045] In another implementation scenario, calculating the start-up compensation temperature based on the insulation parameters includes: determining whether the door opening time of the refrigerator during the current shutdown period is greater than a preset duration, wherein the insulation parameters include the door opening time; if the door opening time of the refrigerator during the current shutdown period is greater than the preset duration, calculating the start-up compensation temperature based on the door opening time, wherein the door opening time is negatively correlated with the start-up compensation temperature.

[0046] The opening and closing sensors of the refrigerator's refrigerator and freezer doors can detect and record the opening time of the refrigerator's compartment doors (including the refrigerator and freezer doors). If the refrigerator door is kept open or the refrigerator door is opened and closed frequently, the refrigerator door will be open for a longer period of time.

[0047] The solution in this embodiment uses the door opening time as a heat preservation parameter to calculate the start-up compensation temperature of the compressor triggered by the freezer compartment. The longer the door opening time, the smaller the start-up compensation temperature and the longer the compressor starts in advance. This can compensate for the decrease in heat preservation capacity and cold air overflow caused by continuous door opening of the refrigerator. It can also solve the problem of refrigerator compartment temperature fluctuation caused by cold air lag due to improper operation of the refrigerator.

[0048] In another implementation scenario, calculating the start-up compensation temperature based on the insulation parameters includes: detecting the average temperature of the food in the refrigerator compartment; calculating the temperature difference between the average temperature and the set temperature of the refrigerator compartment, wherein the insulation parameters include the temperature difference; determining whether the temperature difference is greater than a preset temperature difference; if the temperature difference is greater than the preset temperature difference, calculating the start-up compensation temperature based on the temperature difference, wherein the temperature difference is negatively correlated with the start-up compensation temperature.

[0049] Optionally, temperature sensors such as thermal sensors, infrared temperature sensors, thermocouple sensors, thermistor sensors, and pyroelectric infrared sensors can be used to detect the temperature of food inside the refrigerator. Infrared temperature sensors are based on the infrared radiation characteristics of objects; the higher the temperature of an object, the greater the intensity of its emitted infrared radiation. Thermocouple sensors consist of a closed circuit composed of two metal conductors of different materials. When the temperatures of the two junctions are different, a thermoelectric potential is generated in the circuit. By measuring the magnitude of the thermoelectric potential and performing corresponding calculations, the surface temperature of the object can be obtained. Thermistor sensors utilize the characteristic that the resistance of a thermistor changes with temperature to measure temperature. When a thermistor is in contact with the surface of the object being measured, its temperature changes with the surface temperature, resulting in a change in resistance. By measuring the resistance and referring to the known thermistor characteristic curve, the surface temperature of the object can be calculated. Pyroelectric infrared sensors are based on the pyroelectric effect. When the infrared radiation emitted by the surface of an object is absorbed by the pyroelectric infrared sensor, it causes a temperature change in the pyroelectric material inside the sensor, leading to the generation of charges on the material surface. By detecting these changes in charges, the surface temperature of the object can be measured.

[0050] When users move large amounts of food from outside the refrigerator into the refrigerator compartment, the temperature sensor can detect that the average temperature of the food inside the refrigerator compartment is relatively high.

[0051] Optionally, the temperature difference can also be the temperature difference between the average temperature of the food in the freezer compartment and the set temperature of the freezer compartment. Wherein, temperature difference = average temperature - set temperature of the refrigerator compartment; the larger the temperature difference, the more cooling energy the refrigerator compartment needs to cool the food.

[0052] The solution in this embodiment uses the temperature difference between the set temperature of the refrigerator compartment and the temperature of the food as a heat preservation parameter to calculate the start-up compensation temperature for triggering the compressor to start in the freezer compartment. The larger the temperature difference, the smaller the start-up compensation temperature and the longer the advance time of compressor start-up. This can compensate for the decrease in heat preservation capacity and loss of cold energy caused by the excessively high temperature of the food inside the refrigerator. It can also solve the problem of temperature fluctuation in the refrigerator compartment caused by the lag of cold energy due to a large amount of high-temperature food inside the refrigerator.

[0053] In one embodiment of this example, after controlling the compressor to start in advance based on the first real-time freezing temperature, the first real-time refrigeration temperature, and the insulation parameters, the method further includes: detecting the second real-time freezing temperature of the freezer compartment and detecting the second real-time refrigeration temperature of the refrigeration compartment; determining whether the second real-time freezing temperature is lower than the freezer shutdown temperature and determining whether the second real-time refrigeration temperature is lower than the refrigeration shutdown temperature; if the second real-time freezing temperature is lower than the freezer shutdown temperature and the second real-time refrigeration temperature is lower than the refrigeration shutdown temperature, controlling the compressor to switch from the start state to the stop state.

[0054] Optionally, taking the refrigerator's set temperature as 5℃ and the freezer's set temperature as -15℃ as an example, the refrigerator's shut-off temperature can be set to 0℃ and the freezer's shut-off temperature can be set to -20℃. When the real-time temperature of the refrigerator compartment reaches the refrigerator's shut-off temperature, the air damper between the refrigerator and freezer compartments closes, the freezer compartment no longer provides cooling to the refrigerator compartment, and the temperature of the refrigerator compartment no longer decreases. When the real-time temperature of the freezer compartment reaches the freezer's shut-off temperature, the compressor no longer provides cooling to the freezer compartment.

[0055] By adopting the scheme of this embodiment, when the real-time temperatures of both the freezer and refrigerator compartments meet the corresponding shutdown temperatures, the compressor is controlled to switch from the start state to the stop state. This allows the compressor to be turned off when the temperature of the refrigerator compartment is low, avoiding the rapid dissipation of cold air from the freezer compartment due to the high real-time temperature of the refrigerator compartment, which would cause the freezer compartment temperature to drop rapidly and frequently start the compressor. This avoids frequent compressor start-stop and improves the stability of the refrigerator.

[0056] In this embodiment, taking the factory-set time as an example for the insulation parameter, when the compressor is off, the difference between the refrigerator compartment temperature and the compressor's start-up temperature is used as the trigger condition for forced compressor start-up. This compensates for insufficient cooling supply caused by the decreased insulation performance of the refrigerator compartment, thereby reducing temperature fluctuations and energy consumption. When the refrigerator compartment is turned on for cooling, the freezer compartment's start-up temperature is adjusted based on the factory-set time to compensate for insufficient cooling supply caused by the decreased insulation performance, thus reducing temperature fluctuations in the refrigerator. Figure 3 This is a flowchart of a control method for a frost-cooled refrigerator according to an embodiment of the present invention, including: Step 1: Real-time detection of whether the refrigerator is disconnected from the high-voltage power supply to determine whether it is necessary to cut off the battery power. If so, the mainboard MCU will enter low-power mode and proceed to Step 2; otherwise, proceed to Step 3. Step 2: The main controller MCU is powered by battery and low-power mode is enabled to save battery power. Then proceed to step 4. Step 3: Disconnect the battery power supply circuit and switch to motherboard power supply to save battery power, then proceed to Step 4; Step 4: Record the refrigerator's manufacturing time Y in real time to determine if the refrigerator is too old, then proceed to Step 5; Step 5: Obtain the refrigerator start-up temperature Tc of the refrigerator compartment and the freezer start-up temperature Tf of the freezer compartment to determine whether the compartments have a cooling requirement, and then proceed to Step 6; Step Six: Determine if the refrigerator's manufacturing time Y is less than the threshold Y0 (typically 10 years). If so, it means the refrigerator has good insulation performance and does not need to be set to compensate for the start-up temperature. Proceed to Step Seven. Otherwise, continue to determine the manufacturing time and proceed to Step Eight. Step 7: At this point, the refrigerator's insulation performance is good, and there is no need to set the start-up compensation temperature. Set the freezer compartment start-up compensation temperature to Tfrz0 (typical value is 0 degrees Celsius), and then proceed to step 11; Step 8: Determine if the refrigerator's manufacturing time Y is less than the threshold Y (typically 15 years). If so, it means that the refrigerator's heat preservation performance has declined and the start-up compensation temperature needs to be increased appropriately. Proceed to Step 9. Otherwise, if the refrigerator has been used for too long, its heat preservation performance will be even worse, and a larger start-up compensation temperature is needed to meet the temperature fluctuation requirements. Proceed to Step 10. Step 9: Set the freezer compartment shutdown compensation temperature to Tfrz1 (typical value is -0.5 degrees Celsius), then proceed to Step 11; Step 10: Set the freezer compartment shutdown compensation temperature to Tfrz2 (typical value is -1 degree Celsius), then proceed to Step 11; Step 11: Determine if the refrigerator compartment temperature is greater than or equal to the refrigerator start-up temperature Tc. If so, it means that the refrigerator compartment has a cooling demand and the freezer compartment is providing cooling to the refrigerator compartment. Then, determine the cooling status of the freezer compartment and proceed to Step 12. Otherwise, continue to determine and detect the refrigerator's operating status and proceed to Step 1. Step 12: Determine if the freezer compartment temperature is greater than or equal to the freezer start-up temperature plus the freezer start-up compensation temperature. If so, it means that the compressor cooling function needs to be turned on in advance to prevent excessive temperature fluctuations in the compartment. Proceed to Step 13. Otherwise, continue to check the refrigerator's operating status and proceed to Step 1.

[0057] The solution in this embodiment uses the refrigerator compartment temperature and factory manufacturing date as control factors for compressor start-stop. When the compressor is off, if the temperature difference between the refrigerator compartment and the freezer compartment compressor reaches a threshold, the compressor is forcibly started, ensuring timely control of the refrigerator compartment temperature and preventing delayed cooling supply due to decreased insulation performance. This control strategy effectively reduces refrigerator compartment temperature fluctuations, lowers the compressor's start-up frequency, thereby reducing overall energy consumption and improving refrigerator operating efficiency and user experience.

[0058] This embodiment introduces two variables, namely the refrigeration temperature and the manufacturing time, to appropriately adjust the start-up temperature of the freezer compartment when the refrigerator compartment is turned on for cooling. This avoids lag in cooling capacity and temperature fluctuations in the refrigerator compartments caused by decreased insulation performance, thus solving the problem of poor user experience due to decreased insulation performance after the refrigerator has been manufactured for too long.
